Come on Dima.  I admit that I haven't been working on Sage as much as I
used to, since I've been trying to write papers in order to find a job.
But the claim that I don't want to spend a bit of my time helping general
Sage development is completely ridiculous.  I was involved in the work to
transition to git, in rewriting the doctest framework, implementing
coercion.  And I'm about to organize a Sage Days (though perhaps you don't
count p-adic computation as "general" Sage development).  Are you just
trying to take over for Nathann now that he's gone?

I don't have an *expectation* that people to the work for me.  But I think
I have a right to *request* enhancements.  I think that people who aren't
involved in Sage at all have such a right.

William can speak more to the technical details for SMC, but the project
supposedly has 11GB of RAM, 6 cores (I don't know what kind) and 53GB of
disk space.  We'll probably add more as people arrive for the workshop (I
think that many participants are SMC customers and might be able to
contribute).
